    Analysis of Patient Flow Using Discrete Event Simulation for An Emergency Room: A Case Study of Bhim Hospital Rupandehi, Nepal
    (Pulchowk Campus, 2024-06) Khanal, Sudin; Maharjan, Sanjeev
    The Emergency Room experiences a daily influx of patients, putting significant strain on departmental resources. Concurrently, treatment duration for patients has risen, leading to dissatisfaction and prolonged wait times. Hospital management is exerting maximum effort within existing resources to mitigate these issues, with a primary focus on reducing wait times. To address these challenges, a Discrete Event Simulation is employed to simulate real-world scenarios and identify optimal solutions for reducing length of stay, wait times, and other contributing factors, thus bolstering the foundation for robust decision-making. Bhim Hospital's Emergency Room serves as the case study, assessing wait times, length of stay, and bed utilization. Experimental scenarios are applied to the model, aiding the hospital management team in decision-making processes. Selection and rejection of strategies are based on paired test analyses, comparing real-world hospital data with results generated by the simulation model. Given the feasibility of all scenarios in decreasing length of stay, and bed occupancy rates, the results are recommended to the hospital for implementation. The time to stay for Red zone, Green zone and Yellow zone patients is 6 hours according to hospital data and simulation suggest of 3,4 and 5 hours respectively, this also suggest on decreasing of length of stay in the hospital. The percentage of RED BED occupy by Red zone patients in Base case is 16.64%, whereas for REST BED is 10.06%. Similarly for alternative 2, slight reduction in bed for both RED BED and REST BED of 10.21% and 6.724% respectively. Furthermore, by adding one more Physician decreases bed utilization to 10.62% less then base case and for REST BED to 7.39%. Finally, adding a path lab inside the Emergency room and only one Physician increases the RED BEDS utilization, but decreases in REST BED utilization by 17.097% and 9.467% respectively.

    DESIGN, FABRICATION AND AUTOMATION OF INDUSTRIAL 6-DOF ROBOTIC ARM WITH ON-DEMAND MANUFACTURING CAPABILITIES FOR MASS/BATCH PRODUCTION INDUSTRIES
    (I.O.E, 2024-03) Chaudhari, Abishek; Sah, Gangotri; Timsina, Sameer; Poudel, Sneha; Maharjan, Sanjeev
    Industry 4.0, the fourth industrial revolution, combines digital technologies and automation in manufacturing. This project aims to design and control a six-degree - of freedom robotic arm with counterbalance mechanism and it also incorporates the concept of on-demand manufacturing and uses the model robotic arm to integrate it. The project seeks to enhance manufacturing operations, improve efficiency, and increase productivity. The robotic arm will be driven by servo and stepper motors controlled by Raspberry Pi B+ microcontroller. Real-time communication and control will optimize the manufacturing process, leading to streamlined operations and increased responsiveness. Additionally, weight reduction and counterbalancing mechanism has been implemented to ensure use of cost effective actuators. This project has the potential to transform the manufacturing industry by enabling direct communication between clients and manufacturers, eliminating intermediaries and revolutionizing manufacturing processes.

    Examining the Emergence of Information Technology and its Impact on Third Party Logistics in Nepal
    (I.O.E, 2024-06) Shrestha, Pravat; Maharjan, Sanjeev
    The thesis titled “Examining the emergence of information technology and its impact on third-party logistics in Nepal” explores the integration and influence of information technology (IT) in the context of the third-party logistics (3PL) sector in Nepal. This study explores the increasing significance of IT in enhancing the overall performance, customer service, and operational efficiency of 3PL services in Nepal's logistics industry. It aims to shed light on how IT is transforming logistics and customer experience within Nepal's unique infrastructure and socio-economic context. This will be achieved through a detailed examination of technology adoption, system integration, and industry practices. This study tries to highlight status of third-party logistics in Nepal, IT tools currently they have adopted in their daily operations. This research provides information about current major IT tools required for 3pls and how these 3pls are chosen by clients and customers and what IT tools and other criteria to focus on for competitive advantage. Additionally, this study showcases the challenges the 3pls are facing while integrating tools and the opportunities that exists in this logistics market in Nepal.
